Fixing device for stage sound

Abstract

The invention discloses a fixing device for a stage sound. The fixing device comprises a base, a support platform and a rotary platform, wherein a cylinder seat is arranged on the base, a cylinder isembedded into the cylinder seat, the support platform is fixedly arranged on an output shaft at the tail end of the cylinder, the rotary platform is arranged on the support platform, the lower centerof the rotary platform is connected with one end of a rotating shaft, the other end of the rotating shaft penetrates through the support platform, a motor is arranged at the bottom of the rotating shaft, telescopic rods are arranged at the upper four edges of the rotary platform, a control box is arranged on the base, and a human body infrared sensor, an indicator lamp module, a storage module anda controller are arranged in the control box; and the human body infrared sensor, the indicator lamp module and the storage module are all electrically connected with the controller. Compared with the prior art, the fixing device can be controlled according to operation requirements during use, is quick in operation, time-saving, steady in overall structure and stable in operation, does not produce any impact damage, and at the same time, is simple in structure manufacture, convenient in manual processing and assembly and low in production cost.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to a fixing device for stage audio. Background technique [0002] Now there are many large-scale stage activities, and the sound effect is the most important for the stage activities, and the positioning, placement and orientation of the speakers will have a great impact on the sound effect. Therefore, in order to achieve the best sound effect It is often necessary to adjust and move the position and direction of the speaker. In the past, for the convenience of adjustment and movement, the user basically placed the speaker on the floor on both sides of the stage, etc., but this placement method limited the position of the speaker to adjust up and down. , and must occupy the area of ​​the stage; otherwise, the speakers are hung on the scaffolding around the stage or on the ceiling, which is not only difficult to place, but also inconvenient to move and adjust; of course, ther...
